Bill Tempero (born January 16, 1944) is an American former racing driver from Milwaukee. He raced in the CART Championship Car series from 1980 to 1984 competing in full seasons his first two years and partial schedules thereafter. He failed to qualify for both the races he attempted in 1984, so he was not credited with a race start that season. Tempero finished 20th in CART points in 1980 with two top-10 finishes including his series-best result of 6th place at the Milwaukee Mile while driving for Hopkins Racing. He fielded his own car in 1981 and 32nd in points without a single top-ten. He attempted to qualify for the Indianapolis 500 in 1980, 1981, and 1983 but failed to make the field in 1980 and 1983 and crashed while attempting to qualify in 1981.
